Understanding PII Data
Personally Identifiable Information (PII) is data that can uniquely identify an individual, such as an employee, a patient, or a customer. “Sensitive PII” refers to information that, if compromised, could pose a greater risk to the individual’s privacy and misuse of information for someone else’s gains.
With numerous laws and regulations governing the collection, use, sharing, deletion, and security controls of PII data and sensitive PII, organizations must stay compliant amidst the continuous enactment of new laws. PII data discovery is crucial for maintaining this compliance.
Modern consumers are well-informed about the significance of their data, its potential misuse, and the consequences of its loss. Consequently, regulatory authorities are scrutinizing companies that rely on data collection. To navigate this complex landscape of regulations, organizations must ensure lawful and responsible data usage.
Whether the purpose is data protection, governance, or regulatory compliance, it all starts with understanding the nature of sensitive data, its storage locations, security measures, and the relevant legal frameworks. This underscores the necessity for an effective PII data discovery tool to facilitate these efforts.

What Is PII Data Discovery & Why It Is Important
PII data discovery refers to the process of identifying and locating Personally Identifiable Information (PII) within an organization’s data repositories. PII is any information that can be used to identify a specific individual, either on its own or when combined with other data.
Examples of what constitutes PII include names, addresses, social security numbers, email addresses, phone numbers, financial information, and more. Understanding the benefits of PII data discovery is crucial for organizations to protect sensitive data and maintain compliance.
Consider this scenario: In a marketing campaign, the sales team uses the lead data to convert prospects into paying customers, while the finance team uses the same data to process payments. Furthermore, the product marketing team uses the same data to send periodic product updates to customers.
In this particular example, each department processes the data differently, necessitating potential access to distinct pieces of personally identifiable information (PII). For instance, the finance team requires credit card data to process payments, while the email marketing team relies on customers’ names and email addresses to send emails.
Sales need to know the customer’s full address, and customer success requires a complete product version and purchase history details. However, no single team requires access to all aspects of the data. This may result in the same data being replicated across various siloed databases throughout the organization, making it more difficult to protect personal and sensitive information.
Furthermore, the advent of hyper-scale cloud computing environments, such as Snowflake, has enabled effortless collaboration in the cloud. Employees across most organizations are empowered to access the cloud, perform petabyte-scale queries from various locations, resulting in the generation of vast amounts of data. It is projected that the cloud environment will contain over 100 zettabytes of data by 2025.
In a sense, this cloud data is scattered across multiple platforms and locations such as data lakes, databases, applications, and personal computers. This dispersion leads to a lack of visibility into the data’s security posture or privacy compliance status, exposing companies to potential data breaches or compliance failures.
To address these concerns, the teams responsible for managing data privacy, security, and compliance require seamless visibility and insights into the extent and usage of PII data. A sensitive data discovery tool can provide CISOs and DPOs with comprehensive visibility into the data and its security and compliance status. PII data discovery software plays a crucial role in this process.
Best Practices in PII Data Discovery
To achieve effective PII data protection, organizations must embrace best practices in PII data discovery. Let’s explore the essential best practices that organizations should adopt to ensure the secure and responsible handling of PII data, safeguarding both their reputation and the trust of their customers.
- Identify all data sources:
The first step in PII data discovery is to identify all the data sources within an organization. This includes databases, file servers, cloud storage, third-party systems, and any other repositories where sensitive information might reside. Creating a comprehensive inventory of data sources helps to ensure that no PII is overlooked during the discovery process. - Implement data classification:
Data classification involves categorizing data based on its sensitivity and criticality. This practice helps organizations prioritize their efforts and resources when discovering and protecting PII. By labeling data as public, internal, confidential, or sensitive, organizations can apply appropriate security measures and controls to safeguard PII effectively. PII data discovery and classification go hand in hand for optimal data management. - Data Mapping and Flow: Understanding how PII moves through an organization’s systems is crucial for effective sensitive data discovery. Data mapping involves documenting the flow of information, from its creation to its storage and eventual destruction. This process aids in identifying potential vulnerabilities and points of exposure where PII may be at risk.
- Data Minimization: To minimize the risk of exposure to sensitive PII, organizations should practice data minimization. This means collecting and retaining only the necessary personal information required for specific business purposes. Unnecessary storage of PII increases the potential for data breaches and compliance violations. Right to be forgotten has become necessary for compliance.
- Consent and Transparency: Obtaining explicit consent from individuals before collecting and processing their PII is a fundamental principle of data privacy. Informing users about the purposes and methods of data collection and usage helps build trust and compliance with data protection regulations.
- Access Controls and Masking: Implementing robust access controls ensures that only authorized personnel can access PII. Role-based access, multi-factor authentication, and encryption are some measures that help protect sensitive data from unauthorized use. Additionally, data masking techniques can be used to anonymize PII for certain purposes, reducing the exposure of real user information.
- Regular Data Assessments: Regularly assessing the organization’s data handling practices and security measures is crucial to identify vulnerabilities and address potential weaknesses. PII data discovery should be an ongoing process, adapting to changes in data storage, processing, and the threat landscape.
- Staff Training and Awareness: Ensuring that all employees are trained in data protection policies, best practices, and the importance of handling PII securely is essential. Employees are often the first line of defense against data breaches, and their awareness can significantly mitigate the risk of accidental or intentional data mishandling.
- Incident Response and Notification: Having a well-defined incident response plan is essential in the event of a data breach or security incident. The plan should outline the steps to be taken to mitigate the impact of the breach, including timely notifications to affected individuals and relevant authorities as required by data protection regulations.
- Periodic Reviews and Updates: Sensitive data discovery practices should be periodically reviewed and updated to reflect changes in data handling procedures, technological advancements, and regulatory requirements. Staying proactive and adaptive ensures that the organization maintains a robust PII data discovery and protection framework.
